FAQ

Is my text processed in the browser?

Yes. Conversions happen entirely in your browser; nothing is uploaded to a server.

What’s the difference between Title Case and Capitalized?

Both capitalize words, but Title Case applies to each word like a heading, while Capitalized is a general capitalization for readability.

Does it support non-English characters?

Basic casing works for most Latin-based scripts. Advanced locale-specific rules may vary by browser.
